_I.WARNING: Always disconnect
spark plug wire when making repairs ex-
cept for carburetor adjustments. Be-
cause a chain saw is a high-speed
woodcutting tool, special safety precau-
tions must be observed to reduce risk of
accidents. Careless or impreper use of
this tool can cause serious injury.
PLAN AHEAD
• Restdct the use of your saw to adult
users who understand and can follow
the safety rules, precautions, and op-
ereting instructions found in this
manual.
• Wear protective gear. Always use
steel-toed safety footwear with non-
slip soles; snug-fitting clothing;
heavy-duty, non-slip gloves; eye pro-
tection such as non-fogging, vented
goggles or face screen; an approved
safety hard hat; and sound barriers
(ear plugs or mufflers) to protect your
hearing. Regular users should have

• Secure hair above shoulder length.
Do not wear loose clothing or jewel-
ry; they can get caught in moving
pads.
• Keep all parts of your body away
from the chain when the engine is
running.
• Keep children, bystanders, and ani-
mals at least 30 feet (10 meters)
away from the work area when start-
ing and using the saw.
• Do not handle or operate a chain
saw when you are fatigued, i11,or up-
set, or if you have taken alcohol,
drugs, or medication. You must be in
good physical condition and mentally
alert. If you have any condition that
might be aggravated by strenuous
work, check with doctor before oper-
ating.
• Do not start cutting until you have a
clear work area, secure footing, and
especially if you are felling a tree, a
retreat path.
OPERATE YOUR SAW SAFELY
• Do not operate with one hand. Seri-
ous injury to the operator, helpers, or
bystanders may result from one-
handed operation. A chain saw is in-
tended for two-handed use.
• Operate the chain saw only in a well-
ventilated outdoor area.
• Do not operate saw from a ladder or
in a tree.
• Make sure the chain will not make
contact with any object while starting
the engine. Never try to start the saw
when the guide bar is in a cut.
• Do not put pressure on the saw, es-
pecially at the end of the cut. Doing
so can cause you to lose control
when the cut is completed.
• Stop engine before setting saw down.
• Hand carry saw only when engine is
stopped. Carry with muffler away
from body; guide bar & chain project-
ing behind you; guide bar preferably
covered with a scabbard.
• Do not operate a chain saw that is
damaged, improperly adjusted, or not
completely and securely assembled.
Always replace bar, chain, hand
guard, chain brake, or other parts im-
mediately if they become damaged,
broken, or are otherwise removed.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
• Have all chain saw service per-
formed by a qualified service dealer
except the items listed in the MAINTE-
NANCE section of this manual.
• Make certain the saw chain stops
moving when the throttle trigger is
released. For correction, refer to
CARBURETOR ADJUSTMENTS.
• Keep the handles dry, clean, and
free from oil or fuel mixture.
• Keep caps and fasteners securely
tightened.
• Nonconforming replacement compo-
nents or the removal of safety devices
may cause damage to the unit and
possible injury to the operator or by-

HANDLE FUEL WITH CAUTION
• Do not smoke while handling fuel or
while operating the saw.
• Eliminate all sources of sparks or
flame in areas where fuel is mixed or
poured.
• Mix and pour fuel in an outdoor area
and use an approved, marked con-
tainer for all fuel purposes. Wipe up
all fuel spills before starting saw.
• Move at least 10 feet (3 meters) from
fueling site before starting.
• Turn the engine off and let saw cool
in a non-combustible area, not on
dry leaves, straw, paper, etc. Slowly
remove fuel cap and refuel unit.
• Store the unit and fuel in a cool, dry
well ventilated space where fuel va-
pors cannot reach sparks or open
flames from water heaters, electric
motors or switches, furnaces, etc.
GUARD AGAINST KICKBACK
Follow all safety rules to help avoid
kickback and other forces which can
result in serious injury.
Kickback Path
_, _. _ Avoid _,_uctions
Clear The Working Area
41_WARNING: Avoid kickback which
can result in serious injury. Kickback
is the backward, upward or sudden for-
ward motion of the guide bar occurring
when the saw chain near the upper tip
of the guide bar contacts any object
such as a log or branch, or when the
wood closes in and pinches the saw
chain in the cut. Contacting a foreign
object in the wood can also result in
loss of chain saw control.
• Rotational Kickback can occur
when the moving chain contacts an
object at the upper tip of the guide
bar. This contact can cause the
chain to dig into the object, which
stops the chain for an instant. The
result is a lightning fast, reverse
reaction which kicks the guide bar up
and back toward the operator.
• Pinch-Kickback can occur when the
the wood closes in and pinches the
moving saw chain in the cut along
the top of the guide bar and the saw
chain is suddenly stopped. This sud-
den stopping of the chain results in a
reversal of the chain force used to
cut wood and causes the saw to
move in the opposite direction of the
chain rotation. The saw is driven
straight back toward the operator.
• Pull-In can occur when the moving
chain contacts a foreign object in the
wood in the cut along the bottom of
the guide bar and the saw chain is
suddenly stopped. This sudden stop-
ping pulls the saw forward and away
from the operator and could easily
cause the operator to lose control of
the saw.
REDUCE THE CHANCE OF
KICKBACK
• Recognize that kickback can happen.
With a basic understanding of kick-
back, you can reduce the element of
surprise which contributes to acci-
dents.
• Never let the moving chain contact
any object at the tip of the guide bar.
• Keepworkingareafreefromobstruc-
tionssuchasothertrees,branches,
rocks,fences,stumps,etc.Eliminate

Avoid Pinch-Kickback:
• Be extremely aware of situations or
obstructions that can cause material
to pinch the top of or otherwise stop
the chain.
• Do not cut more than one log at a
time.
• Do not twist saw as bar is withdrawn
from an undercut when bucking.
Avoid Pull-In:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of plastic or
wood. Never use metal to hold the
cut open,
MAINTAIN CONTROL
Stand to the left of the saw
underside
_-_-_ t Elbow
ed
Never reverse hand positions
• A good, firm grip on the saw with
both hands will help you maintain
control, Don't let go, Grip the rear
handle with your right hand whether
you are right or left handed, Wrap the
fingers of your left hand over and
around the front handlebar, and your
left thumb under the front handlebar,
Keep your left arm straight with the
elbow locked.
• Position your left hand on the front
handlebar so it is in a straight line
with your right hand on the rear han-
dle when making bucking cuts.
Stand slightly to the left side of the
saw to keep your body from being in
a direct line with the cutting chain.
• Stand with your weight evenly bal-
anced on both feet.
• Do not overreach. You could be
drawn or thrown off balance and lose
control.
• Do not cut above shoulder height. It
is difficult to maintain control of saw
above shoulder height.
KICKBACK SAFETY FEATURES
_WARNING: The following fea-
tures are included on your saw to help
reduce hazard of kickback; however,
such features will not totally eliminate
this danger. Do not rely only on safety
devices. Follow all safety rules to help
avoid kickback and other forces which
can result in serious injury.
• Front Hand Guard: designed to re-
duce the chance of your left hand
contacting the chain if your hand
slips off the front handlebar.
• Position of front and rear handlebars:
designed with distance between han-
dles and "in-line" with each other. The
spread and "in-line" position of the
hands provided by this design work
together to give balance and resis-
tance in controlling the pivot of the
saw back toward the operator if kick-
back occurs,
• Reduced-Kickback Guide Bar: de-
signed with a small radius tip which
reduces the size of the kickback
danger zone, This type bar has been
demonstrated to significantly reduce
the number and seriousness of kick-
backs.

• Chain Brake: designed to stop the
chain in the event of kickback,
_WARNING: WE DO NOT REP*
RESENT AND YOU SHOULD NOT AS_
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OF A KICK*
BACK. Kickback is a lightning fast action
which throws the bar and rotating chain
backand uptoward the operator. Kick-
back can be caused by allowing contact
of the bar tip in the danger zone with any
hard object. Kickback can also be
caused by pinching the saw chain along
the top of the guide bar, This action may
push the guide bar rapidly back toward
theoperator, Either of these events may
cause you to lose control of the saw
which could result in serious injury or
even death, DO NOT RELY UPON ANYOF
THE DEVICES BUILT INTO YOUR SAW.
YOU SHOULD USE THE SAW PROPERLY
AND CAREFULLY TO AVOID KICKBACK.
Reduced-kickback guide bars and low-
kickback saw chains reduce the chance
and magnitude of kickback and are rec-
ommended, Your saw has a low kick-
back chain and bar as original equip-
ment. Repairs on a chain brake should
be made by an authodzed Sears Service

IAFETY NOTICE: Exposure to vibra-
tions through prolonged use of gasoline
powered hand tools could cause blood
vessel or nerve damage in the fingers,
hands, and joints of people prone to
circulation disorders or abnormal swell-
ing. prolonged use in cold weafl_er has
been linked to blood vessel damage in
otherwise healthy people. If symptoms
occur such as numbness, pain, loss of
Centre. Take your unit to the place of pur-
chase or to your nearest Sears Service
Centre.
• Tip contact in some cases may cause
a lightning fast reverse REACTION,
kicking guide bar up and back toward
operator.
• Pinching the saw chain along the top
of the guide bar may push the guide
bar rapidly back toward the operator.
• Either of these reactions may cause
you to lose control of the saw which
could result in serious injury. Do not
rely exclusively upon safety devices
built into your saw.
_WARNING: Computed kickback
angle (CKA) listed on your saw and
listed in the CKA table below represents
angle of kickback your bar and chain
combinations will have when tested in
accordance with CSA (Canadian Stan-
dards Association) standards. When
purchasing replacement bar and chain,
considerations should be given to the
lower CKA values. Lower CKA values
represent safer angles to the user, high-
er values indicate more angle and high-
er kick energies. Computed angle repre-
sented indicates total energy and angle
associated without activation of the
chain brake dudng kickback. In all cases
lower CKA values represent a safer op-
erating environment for the user.
The following guide bar and chain com-
binations meet kickback requirements
of CSA 2162.1 & Z62.3 when used on
saws listed in this manual. Use of bar
and chain combinations other than
those listed is not recommended and
may not meet the CKA requirements per
standard.

and seek medical attention. An anti-vi-
bration system does not guarantee the
avoidance of these problems. Users
who operate power tools on a continual
and regular basis must closely monitor
their physical condition and the condition
of this tool.
SPARK ARRESTING SCREEN: Your
saw is equipped with a temperature
limiting muffler and spark arresting
screen which meets the requirements
of California Codes 4442 and 4443. All
U.S. forest land and the states of Cali-
fornia, Idaho, Maine, Minnesota, New
Jersey, Oregon, and Washington re-
quire by law that many internal com-
bustion engines be equipped with a
spark arresting screen. If you operate
a chain saw in a state or locale where
such regulations exist, you are legally
responsible for maintaining the operat-
ing condition of these parts. Failure to
do so is a violation of the law. Refer to

signed to stop the chain if kickback oc-
curs. The chain brake activates auto-
matically in the event of kickback. The
chain brake activates manually if the
front hand guard is pushed forward.
The chain brake is disengaged by pull-
ing the front hand guard back toward
the front handle as far as possible.
CHAIN TENSION
It is normal for a new chain to stretch
dudng first 30 minutes of operation. You
should check your chain tension fre-
quently. See CHAIN TENSION under the
SERVICE AND ADJUSTMENTS section.
_WARNING: Muffler is very hot
during and after use. Do not touch the
muffler or allow combustible material
such as dry grass or fuel to do so.
BEFORE STARTING ENGINE
_WARNING: Be sure to read the
fuel handling information in the safety
rules section of this manual before you
begin. If you do not understand the
fuel handling information do not at-
tempt to fuel your unit. Seek help from
someone that does understand the in-
formation or contact your Sears Ser-
vice Centre.
GUIDE BAR AND CHAIN OIL
The chain oiler provides continuous
lubrication to the chain and guide bar.
Be sure to fill the bar oil tank when you
fill the fuel tank (Capacity = 6.8 fl. oz.),
For maximum guide bar and chain life,
we recommend you use Craftsman
chain saw bar oil, If Craftsman bar oil
is not available, you may use a good
grade SAE 30 oil until you are able to
obtain Craftsman brand. The oil output
is automatically metered during opera-
tion. Your saw will use approximately
one tank of bar oil for every tank of fuel
mix. Always fill the bar oil tank when
you fill the fuel tank.
FUELING ENGINE
_WARNING: Remove fuel cap
slowly when refueling,
This engine is certified to operate on un-
leaded gasoline, Before operation, gaso-
line must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil.
We recommend CraBsman brand syn-
thetic oil. Mix gasoline and oil at a ratio
of 40:1. A 40:1 ratio is obtained by mix-
ing 3,2 ounces (95 ml) ofoil with 1 gal-
lon (4 litres) of unleaded gasoline. In-
cluded with this saw is a 3,2 ounce (95
ml) container of Craftsman brand oil.
Pour the entire contents of this container
into 1 gallon (4 litres) of gasoline to
achieve the proper fuel mixture. DO NOT
USE automotive oil or boat oil, These oils
will cause engine damage, When mixing
fuel follow the instructions printed on the
container. Once oil is added to the gaso-
line, shake container momentarily to as-
sure that the fuel is thoroughly mixed.
Always read and follow the safety rules
relating to fuel before fueling your unit,
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract mois-
ture which leads to separation and
formation of acids durthg storage. Acidic
gas can damage the fuel system of an
engine while in storage,
To avoid engine problems, the fuel
system should be emptied before stor-
age for 30 days or longer, Drain the
gas tank, start the engine and let it run
until the fuel lines and carburetor are
empty. Use fresh fuel next season.
See STORAGE instructions for addition-
al information.
Never use engine or carburetor clean-
er products in the fuel tank or perma-
nent damage may occur.
See the STORAGE section for addition-
al information.
CHAIN BRAKE
Ensure chain brake is disengaged by
pulling the front hand guard back to-
ward the front handle as far as pos-
sible. The chain brake must be disen-
gaged before cutting with the saw.
_WARNING: The chain must not
move when the engine runs at idle
speed, If the chain moves at idle
speed refer to CARBURETOR ADJUST*
MENT within this manual, Avoid con-
tact with the muffler. A hot muffler can
cause serious burns.
STOPPING YOUR ENGINE
• Move ON/STOP switch to the STOP
position.
STARTING YOUR ENGINE
• To start the engine, hold the saw
firmly on the ground as illustrated.
Make sure the chain is free to turn
without contacting any object,

the unit is flooded. If engine fails to
start, refer to the TROUBLESHOOTING
TABLE or contact your Sears Service
Centre.
CHAIN BRAKE
£A _
I_WARNING: If the brake band is
worn too thin it may break when the chain
brake is triggered. With a broken brake
band, the chain brake will not stop the
chain. The chain brake must be replaced
if any part is worn to less than 0.020 inch
(0.5 mm) thick. Repairs on a chain brake
should be made by your Sears Service
Centre. Take your unit to the place of pur-
chase or to the nearest Sears Service
Centre.
• This saw is equipped with a chain
brake. The brake is designed to stop
the chain if kickback occurs.
• The inertia-activated chain brake is ac-
_vated if the front hand guard is pushed
forward, either manually (by hand) or
automa%ally (by sudden movement).
• If the brake is already activated, it is
disengaged by pulling the front hand
guard back toward the front handle as
far as possible.
• When cutting with the saw, the chain
brake must be disengaged.
Disengaged
Braking function control
CAUTION: The chain brake must be
checked several times daily. The engine
must be running when performing this
procedure. This is the only instance
when the saw should be placed on the
ground with the engine running.
10
Place the saw on firm ground. Grip the
roar handle with your right hand and the
front handle with your left hand. Apply full
throttle by fully depressing the throttle trig-
ger. Activate the chain brake by turning
your left wrist against the hand guard
without releasing your grip around the
front handle. The chain should stop im-
mediately.
Inertia activating function control
_WARNING: When performing the
following procedure, the engine must
be turned off.
Grip the rear handle with your right hand
and the front handle with your left hand.
Hold the chain saw approximately 14
inches (35 cm) above a stump or other
wooden surface. Release your grip on
the front handle and use the weight of
the saw to let the tip of the guide bar
fall forward and contact the stump.
When the tip of the bar hits the stump,
the brake should activate.
OPERATING TIPS
• Check chain tension before first use
and after 1 minute of operation. See
CHAIN TENSION in the MAINTENANCE
section.
• Cut wood only. Do not cut metal,
plastics, masonry, non-wood building
materials, etc.
• Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair parts as necessary.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility of kickback.
• Practice cutting a few small logs us-
ing the following steps. This will help
you get the "feel" of using your saw
before you begin a major sawing op-
eration.
• Squeeze the throttle trigger and al-
low the engine to reach full speed
before cutting.
• Begin cutting with the saw frame
against the log.
• Keep the engine at full speed the
entire time you are cutting.
• Allow the chain to cut for you. Exert
only light downward pressure.
• Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. If you run the
saw at full throttle without a cutting
load, unnecessary wear can occur.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop engine before setting saw down.
TREE FELLING TECHNIQUES
_WARNING: Check for broken or
dead branches which can fall while
cutting causing serious injury. Do not
cut near buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be able to see well, nor during bad
weather such as rain, snow, or strong
winds, etc.
• Carefully plan your sawing operation
in advance.
• Clear the work area. You need a
clear area all around the tree so you
can have secure footing.
• The chain saw operator should keep
on the uphill side of the terrain as the
tree is likely to roll or slide downhill
after it is felled.
• Study the natural conditions that can
cause the tree to fall in a particular
direction. These conditions include:
• The wind direction and speed.
• The lean of the tree. The lean of a
tree might not be apparent due to
uneven or sloping terrain. Use a
plumb or level to determine the di-
rection of tree lean.
• Weight and branches on one side.
• Surrounding trees and obstacles.
• Look for decay and rot. If the trunk is
rotted, it can snap and fall toward the
operator.
• Make sure there is enough room for
the tree to fall. Maintain a distance of
24/2 tree lengths from the nearest
person or other objects. Engine
noise can drown out a warning call.
• Remove dirt, stones, loose bark,
nails, staples, and wire from the tree
where cuts are to be made.

FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the
tree in the desired direction of fall. After
a felling cut is made on the opposite
side of tree, the tree will tend to fall in
the direction of the notch.
NOTE: If tree has large buttress roots,
remove them before making the notch.
If using saw to remove buttress roots,
keep saw chain from contacting
ground to prevent dulling of the chain.
NOTCH CUT AND FELLING TREE
• Make notch cut by cutting the top of
the notch first. Cut through 1/3 of the
diameter of the tree. Next complete
the notch by cutting the bottom. See
illustration. Once the notch is cut, re-
move the wedge of wood from tree.
Fellingcut here
First cut ='i
• After removing the wood, make the
felling cut on the opposite side of the
notch. This is done by making a cut
about two inches higher than the
center of the notch. This will leave
enough uncut wood between the fell-
ing cut and the notch to form a hinge.
This hinge will help prevent the tree
from falling in the wrong direction.
Hinge holds tree on
stump and helps
Opening of

Closing
of notch
NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of
fall. To avoid kickback and chain
damage, use wood or plastic wedges,
but never steel or iron wedges.
• Be alert to signs that the tree is
ready to fall: cracking sounds, widen-
ing of the felling cut, or movement in
the upper branches.
• As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
• DO NOT use your saw to cut down a
partially fallen tree. Be extremely
cautious with partially fallen trees
that may be poorly supported. When
a tree doesn't fall completely, set the
saw aside and pull down the tree
with a cable winch, block and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired log size.
_,WARNING: Do not stand on the
log being cut. Any portion can roll
causing loss of footing and control. Do
not stand downhill of the log being cut.
IMPORTANT POINTS
• Cut only one log at a time.
• Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
• Use a sawhorse to cut small logs.
Never allow another person to hold
the log while cutting and never hold
the log with your leg or foot.
• Do not cut in an area where logs,
limbs, and roots are tangled. Drag logs
into a clear area before cutting them.
BUCKING TECHNIQUES
_WARNING: If saw becomes
pinched or hung in a log, don't try to
force it out. You can lose control of the
saw resulting in injury and/or damage
to the saw. Stop the saw, drive a
wedge of plastic or wood into the cut
until the saw can be removed easily.
Restart saw and carefully reenter the
cut. Do not use a metal wedge. Do not
attempt to restart your saw when it is
pinched or hung in a log.
Use a wedge to remove pinched saw
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins on the top side of
the log with the bottom of the saw
against the log. When overcutting use
light downward pressure.
12
Overcutting Undercutting
Undercutting involves cutting on the
underside of the log with top of saw
against the log. When undercutting
use light upward pressure. Hold saw
firmly and maintain control. The saw
will tend to push back toward you.
_WARNING: Never turn saw up-
side down to undercut. The saw can-
not be controlled in this position.
Always make your first cut on the
compression side of the log. The com-
pression side of the log is where the
pressure of the log's weight is concen-
trated.
First cut on compression side of log

Second cut
Firstcut on compression side of log
BUCKING WITHOUT A SUPPORT
• Overcut through 1/3 of the diameter
of the log.
• Roll the log over and finish with a
second overcut.
• Watch for logs with a compresion
side. See illustrations for cutting logs
with a compression side.
BUCKING USING A LOG OR
SUPPORT STAND
• Remember your first cut is always on
the compression side of the log. (Re-
fer to the illustrations below for your
first and second cut).
• Your first cut should extend 1/3 of the
diameter of the log.
• Finish with your second cut.

LIMBING AND PRUNING
_,WARNING: Be alert for and
guard against kickback. Do not allow
the moving chain to contact any other
branches or objects at the nose of the
guide bar when limbing or pruning. AI-
bwing such contact can result in seri-
ous injury.
_WARNING: Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any po-
sition which can cause you to lose
your balance or control of the saw.
IMPORTANT POINTS
• Watch out for springpoles.
Springpoles are small size limbs
which can whip toward you, or pull
you off balance. Use extreme cau-
tion when cutting small size limbs.
• Be alert for springback. Watch out for
branches that are bent or under
pressure. Avoid being struck by the
branch or the saw when the tension
in the wood fibers is released.
• Frequently clear branches out of the
way to avoid tripping over them.
LIMBING
• Limb a tree only after it is cut down.
• Leave the larger limbs underneath
the felled tree to support the tree as
you work.
• Start at the base of the felled tree
and work toward the top, cutting
branches and Jimbs. Remove small
limbs with one cut.
13
• Keep the tree between you and the
chain.
• Remove larger, supporting branches
with the cutting techniques described
in BUCKING WITHOUT A SUPPORT.
• Always use an overcut to cut small
and freely banging limbs. Undercut-
ting could cause limbs to fall and
pinch the saw,
PRUNING
_WARNING: Limit pruning to limbs
shoulder height or below, Do not cut if
branches are higher than your shoul-
der. Get a professional to do the job,
• Make your first cut 1/3 of the way
through the bottom of the limb, This
cut will make the limb sag so that it
falls easily on the second cut.
• Next make a second cut an overeut
all the way through the limb,
• Finish the pruning operation by using
an overcut so that the stump of the
limb protrudes 1 to 2 inches from the
trunk of the tree.

CHECK CHAIN TENSION
_WARNING: Wear protective
gloves when handling chain. The
chain is sharp and can cut you even
when it is not moving.
Chain tension is very important.
Chains stretch during use. This is es-
pecially true during the first few times
you use your saw. Always check
chain tension each time you use and
refuel your saw.
1. Use the screwdriver end of the
chain adjustment tool (bar tool) to
move chain around guide bar to
ensure kinks do not exist. The
chain should rotate freely.

2. Loosen chain brake nuts until they
are finger tight against the chain
brake.
3. Turn adjusting screw clockwise un-
til chain solidly contacts bottom of
guide bar rail.
Adjusting
4. Using bar tool, roll chain around
guide barto ensure all links are in
bar groove.
5. Lift up tip of guide bar to check for
sag. Release tip of guide bar, then
turn adjusting screw until sag does
not exist.
6. While lifting tip of guide bar, tighten
chain brake nuts securely with the
bar tool.
7. Use the screwdriver end of the bar
tool to move chain around guide
bar.
8. If chain does not rotate, it is too tight.
Slightly loosen chain brake nuts and
loosen chain by turning the adjusting
screw counterclockwise. Refighten
chain brake nuts.
9. If chain is too loose, it will sag be-
low the guide bar. DO NOT operate
the sawif the chain is loose.
_WARNING: If the saw is operated
with a loose chain, the chain could
jump off the guide bar and result in se-
rious injury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP*
ENING in the SERVICE AND ADJUST-
MENTS section.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the
cut.
• Inadequate supply ofoil to bar/chain.
Check the condition of guide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult.

stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow
the mix instructions found on stabilizer
containers. Run engine at least 5 min-
utes after adding stabilizer.
Craftsman 40:1,2-cycle engine oil (air
cooled) is especially blended with fuel
stabilizer. If you do not use this Sears
oil, you can add a fuel stabilizer to your
fuel tank.
ENGINE
• Remove spark plug and pour 1 tea-
spoon of 40:1, 2-cycle engine oil (air
cooled) through the spark plug open-
ing. Slowly pull the starter rope 8 to
10 times to distribute oil.
• Replace spark plug with new one of
recommended type and heat range.
• Clean air filter.
• Check entire unit for loose screws,
nuts, and bolts. Replace any dam-
aged, broken, or worn parts.
• At the beginning of the next season,
